120 W DIN Rail Power Supplies

120 W DIN Rail Power Supplies prices and range: 7 models with current prices, stock status and specifications at Welibaba. A DIN rail power supply is a switch-mode power supply that clips onto the DIN rail inside a panel and converts mains voltage into regulated DC voltage. It is used in automation panels to provide the 24 V DC supply for PLCs, I/O modules, sensors, relay coils, HMIs and communication devices. In this category, Isıso, ABB CP series, Delta Electronics Lyte 2 and Omron S8VK models are listed with 5 V, 12 V, 24 V and 48 V DC outputs, ratings such as 60 W, 120 W, 240 W and 480 W, and output currents such as 2.5 A, 5 A, 10 A and 20 A. Select the output voltage according to the operating voltage of the devices to be supplied, the rated current according to the total load current, the input voltage according to the mains, and the body width according to the free space on the rail. On many products the output voltage adjustment range is also specified. Manufacturers define the mounting position and ventilation clearance in the datasheet; output power may drop at high ambient temperature. A DIN rail power supply does not maintain its output when the mains is lost; it is not a substitute for a battery-backed DC UPS module in circuits that require uninterrupted 24 V DC.
